SPRING-WHEEL aesaaea Specification of Letters Patent.

Patented nee. a, mi.

Application filed November 24, 1917. Serial No. 203,701.

To all whom it may concern:

Be it known that I, PATRICK HENRY Mc- COURT, a citizen of the UnitedStates, and resident of St. Louis, Missourhhave invented certain new anduseful Improvements in Spring-Wheels, of which the following is aspecification, containing a full, clear, and exact description,reference being had to the accompanying drawings, forming a part hereof.

My invention relates to an improved spring wheel, and it consists in thenovel construction and combination of parts hereinafter particularlydescribed and claimed.

The object of my invention is to rovide an improved spring wheel, whichwi I avoid the necessity of using the expensive pneumatic tire,- whileadording the requisite resiliency for durability and comfort, and.

which wheel will be simple in'construction, not liable to get out oforder during use, and yet be of low cost.

ln the drawings,

Figure 1 is a side elevation of a spring wheel constructed in accordancewith my in vention, the lower half of the guard-ring and spokes beingshown as cut off and removed, to afford a better view of the parts.

Fig. 2 is a vertical section of the principal arts ofthe wheel, lookingin the direct1on indicated by the arrows of the line 2-2 of Fig. 3 is adetail edge-view of two sections of the sectional rim, and

Fig. 4 is a plan view of the said rim sections, showin the form of thetelescopic joint at the en s of said sections.

The numeral 1 designates any common form of a hub, to-which the innerends of the spokes .2 are connected in anyordinary manner, the' outerportions of said s okes being formed with odsets 3 which rest rmly uponthe inner periphery of a stron metal ring 4, and are secured to saidring y suit able fastening devices, such as bolts, screws orpins5.

lRadial extensions of said spokes beyond the said odsets 3 are providedat their outer ends with enlargements or heads 6, which are'icurved tofit the side and edge of a guard-ring 7 which is lL-shaped incross-section. Suitable rivets 8 are used to fasten the said heads 6 tothe said guard-ring 7 or, if preferred by the manufacturer, t ese headsmay be welded to said ring by any well-known electric-weldingapparatus.-

The tire-rim is made in segmental sections 9, there being preferably aseparate section for each one of the S-shaped steel springs 10, and eachsection is provided with an en-. larged socket 11 in which the end ofthe adjacent section is telescopically located, whereby all of saidsections may move relative to each other, and form a flexible rim,capable of expanding and contracting during operation upon the road orstreet. r

The said expanding and contracting flexible rim is, in the presentillustration of my invention made substantially ll-shaped incross-section, to receive the'ordinary solid rubber tire 12, which isheld in place by the usual wires 14, or by any other common or usualmeans.

the said ring 4, and their outer ends fixed to the inner surface of thesections, by rivets 15 or other common means.

The operation of my invention will be read' y apparent, and furtherdescription is unnecessary except to point out that the hub 1, spokes 2,ring 4, and guard-ring 7, are all supported by the said springs, andwill move together during operation, the resiliency of said springspermitting a free movement of said parts as a whole independently oftherim sections 9 and the solid tire 12, the said guard ring 7 slidingouter edge of the said rim sections and tire, and protecting the same aswell as the outer ends of the springs from injury by contact with thecurb or other obstructionaas well as preventing the entrance of mud anddirt to the space between the springs and the rim sections.

I claim:

-1. An improved spring wheel, composed of a suitable hub, spokes havingodsets,

spoke-extensions pro ecting radially. from said offsets, a strong ringto which said odsets. are attached, a rim, resilient devices,

located in the space between said ring and said rim, and a guard-ringextending around the edge of said rim and secured to the outer ends ofsaid spoke-extensions.

2. An improved spring wheel, comosed of a suitable hub, spokes havingosets, spoke-extensions projecting radially from said odsets, a strongring to which said odscts are attached, a flexible contracting andexpanding rim made of telescopic-sections, resilient devices located inthe space between up and down at the Mid ltd

said strong ring and said rirn, and a guardname to this specification inpresence of two rin to which the outer partionsi of saild subscribingwitnesses. spo e-extens ons are secure sai guar ring extending aroundthe edge of the said PATRICK HENRY MCCOURT' 5 telescopic rim-sections,to protect same from Witnesses:

dirt and injury. FRANCES Hooves RosENBAUM,

In testimony whereof I have signed my JOHN C. HIGDON.
